PaQ WaK
Hello, never seen a way to grab an attribute like that in a parameter channel (you probably should use a prim or point expression to lookup the value).
I had to try myself, so here's a little setup using chops to drive the sim time scale from the envelope (magnitude signal) of an audio file.
Thank you PaQ, I solved my problem now, by using the channel wrangle node.
The reason why I didn't use the code chop("/...") is because that I wanted it to give the value a condition
but I noticed that the timescale in pyrosolver couldn't be driven by a point attribute.
I looked at your hip today, and it inspired me that I can modify my audio signal instead of create an attribute in the sop,
so I did it with the channel wrangle node in chop network.
Thank you again for your solution!
it was really simple and helpful!
